We just had a discussion: a branch never S0C4's (short version).

Is the storage x'90'(,R7) fetchable?

Subject: S0C4-11 abend caused by BASSM to address with all X'00' bytes

I'm confused. Can I not see the obvious?


We've got an S0C4-11 abend in a batch job. The last instructions seem to be 

L R15,x'90'(,7)
BASSM R14,R15

R15 has the address that is seen in the PSW in the dump. The storage at this
address *is* in the dump, and it contains a couple of X'00'. 


How can the storage be in the dump when the abend code suggests it is not
even getmained (S0C4-11)? Why is this not an S0C1 (operation exception
caused by X'0000' at the PSW NSI address)?
